Bovine leukosis virus widely infects U.S. dairy herds. The virus has long been thought to be specie-specific. However, research at the University of California-Berkeley has shown that bovine leukosis can infect people. The study also raises questions about a possible role in breast cancer.

Bovine leukosis virus is blood-borne. To prevent its spread on a dairy, use single-use needles and disinfect surgical-type equipment, like certain castrating and dehorning tools that draw blood.

Conjunctival prolapse is one sign of bovine leukosis.
